PICTUBE-I-IOOK.

Specification of Letters Patent.

Patented Jan. 2, 1917.

Application filed January 18, 1916. Serial No. 72,788.

To all whom it may concern:

Be it known that I, MARTIN DEI-IN, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Picture-Hooks, of which the following is a specification.

My invention relates to improvements in picture hooks of the type which are disclosed in United States Letters Patent No. 1,039,367, granted to me under date of September 24, 1912.

An important object of the invention is to provide a hook of the above mentioned character, having simple means whereby the body portion of the hook may be conveniently broken from the point or prong I which has been driven into the wall, and such point or prong remain permanently embedded in the wall, preventing disfigur ing or injuring the wall by its removal.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings forming a part ofthis specification and in which like numerals areemployed to designate like parts throughout the same, Figure 1 is a perspective view of the hook or device embodying the invention. Fig. 2 is a side elevation of the same, and, Fig. 3 is a detail section taken on line 33 of Fig. 2.

In the drawings, wherein for the purpose of illustration is shown a preferred embodi ment of my invention, the hook or device is shown as preferably formed of a single section of wire which is flexible and relatively nonresilient, but sufficiently stiff to with-. stand improper bending. The. term a flexible and relatively nonresilient metal is intended to cover ametal which may be bent into a' loop, which when stretched or distorted will retain its new shape or form. This metal when sharply or locally bent will be readily breakableor frangible. When thus sharply or locally bent, the bent portion will break when one portion of the metal is moved with relation to the other. The device comprises a body portion 5, embodying one or more loops 6 and 7. The loop 6 has anupstanding shank 8, carrying a relatively long wall penetrating point or prong 9, the free end of which is sharpened or pointed, as shown at 10. In forming the prong 9, the material of the wire is bent at the upper end of the shank 8, providing a sharply bent connecting readily breakable portion or member 11. In forming this readily breakable connecting member, pressure is preferably applied to the wire at site directions, as clearly shown at 14%., m

Fig. 3. I have found that a suitably flexible but nonresilient metal, from which the wire is made, will readily break if its material is sharply bent and strained at the point of bending, upon the wire being bent back or straightened out. While the material of the wire is thus strained at its point of bending so that it is readily breakable upon being st aightened out, yet I have found that the s me does not unduly weaken the hook, w en suspending a picture or the like. The

op 7 carries a depending shank 14, prov ded at its end with a preferably upwardly extending prong 15, to engage with a picture frame, eye bolt or other element carried thereby.

In the use of the devices, two of them are secured to the wall in approximate hori zontal alinement, by driving the prongs 9 into the wall, until theshanks 8 preferably contact therewith. The picture is then suspended by or upon the prongs 15, and if it needs ad ustment to assume a true hori- Zontal position, it is effected by pulling down the higher end of the picture frame, the body portion -5 of the device being extensible. When it is desired to detach the device from the wall, the picture frame is removed therefrom, and the body portion and shank 8 swung upwardly and bent upon the connecting member 11, for straightening out the wire at this point. Owing to the strained condition of the metal in the connecting member 11 the shank 8 breaks from 1 the prong 9 at the point 11, while the prong 9 remains embedded in the wall. If the free end of this prong should project out beyond the wall, the same is tapped with a hammer or the like until it is flush with the wall. When the wall is covered with plain paper I have found that the prong 9 embedded therein is only slightly visible'but when a figured paper is upon the wall, such prong is practically invisible.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape,

size, and arrangement of parts may be re sorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described the invention, I

one prong and the body portion being bent and subjected to adegree of pressure such that it is rendered'frangible and breakable upon the relative movement of the body portion with relation to the prong.

2. A hook for suspending pictures or the like, formed of a'fle-Xible and relatively nonresilient metal and embodying a looped body portion carrying prongs at its upper and lower ends which are integral therewith, the metal at the point of connection between the upper prong and body portion being bent and subjected to such a degree of pressure so that the bent portion is strained and bulges laterally and outwardly and is frangible, said locally bent portion being adapted to breakupon the movement of the body portion with relation to the upper 31' prong.

' 3'. A hook for suspending pictures or the like formed of a flexible and relatively nonresilient' metal and embodying a looped body portion carrying prongs at its upper and lower ends which are integraltherewith, the metal at the point of connection between the upper prong and body portion being bent and subjected to such a degree of pressure thatit has a substantially greater 'de' gree of frangibility than the body portion, and said'locallybent portion being adapted to be broken by a single upward'movement of the body portion with respect to the. up- 45 per prong.
